It's really an amazing tank from many points of view! Great job Alessandro! Hei, I know that man :beer:
As far as aquascaping is concerned, I still think that Steve Weast is no. 1, and Richard Harker is no. 2

. They both made something very close to a specific reef zone.
But to be honest, when you see Alessandro's tank the only word you can say is... WOW, no matter if it looks like a candy store, or a pile-o'-rocks or whatever.
I think that there's a trade off between "natural looking" and variety of species of contrasting colors.
BTW, japanese tank are good examples of the art of aquascaping, I love them, but are those bonsai-reefs also natural looking tanks?
EVC bulbs: check Sanjay Joshi test, it seems that the spectrum is very very complete, no "holes" in it, no integration required.
GH method: Alessandro switched back to the zeovit method, he just tried the other one to improve growth. I'm sorry I have no more info on the GH method, but I won't be worried about it...
